Nick Huggins from Permacultureexchange.org.au introduces us to regenerative farming techniques such as the P.A. Yeomans method of keyline pattern plowing.
The Yeoman plow is used to rip compacted soil (mostly mismanaged pasture land) to create off-contour water infiltrating mini-trenches.
The Off-contour patterned “mini-trenches” will not only reduce run off, but also allow precipitation to be redirected towards high points or ridges that are normally shedding water away.
Water once infiltrated, enables fast regrowth, further slowing run-off and its devastating consequences (gully erosion, etc…).
Here follows pictures of the technique :
